The four Bunker children—there were six of them, and you will meet the other two soon. The four Bunker children were playing up in the attic of their home. The attic was not as large as the attic of Grandpa Ford's house on Great Hedge Estate nor were there so many nice things in it. But still it did very well on a rainy afternoon, and Russ, Margy, Violet and Mun Bun were having a good time on the "scooter" Russ had made.

The way Russ made a "scooter" was this. He found a long board, one that the carpenters had left after they had made a storeroom for Mrs. Bunker in the attic, and to the board he fastened, on each end, part of an old roller skate. This gave the scooter two wheels on either end. The wheels were not very large, nor very wide, and unless you sat right in the middle of the board of the scooter you might get tipped over. This had happened several times, and when Mun Bun was on, having a ride, he not only tipped over, but he ran into a trunk that stood in the attic, and knocked off one of the skates.

"Now I have to tie it on again!" Russ had exclaimed, and this had caused a stop in the fun.

"Can you fix it?" asked Margy, as she watched her brother. She wanted another ride, for the one she had had was a short one. Mun Bun was the youngest of the six little Bunkers, and they generally let him have more turns than any one else.

"Oh, yes, I can fix it," said Russ, who now began to whistle. And when Russ whistled, when he was making anything, you could generally tell that everything was coming out right.

Russ very often made things, but he did not always whistle over them. Often the things he made were such a puzzle that he could not think how to make them come out right and also think of a whistle-tune at the same time. But now he was all right, and so he whistled merrily as he put more string on the roller skate that he was fastening to the board of the scooter.

"Is it almost done?" asked Mun Bun, leaning over eagerly.

"Almost," answered Russ. "I want to look at the back wheels to see if they're all right, and then you can have a ride."

Russ gave the string a last turn, tied several knots in it, and then turned the board around. As he did so Margy uttered a cry.

"Ouch!" she exclaimed.
